IMPROVEMENT IN TEMPORARY BINDERS.

Specification forming part of Letters Patent No. 147,527, dated February17, 1874; application filed November 11, 1873.

To all whom it may concern:

Be it known that I, GEORGE SwEA'r'l, of Lebanon, county of Grafton andState of New Hampshire, have invented an Improved Temporary Binder, ofwhich the following is a specification M y invention relates to devicesfor holdin leaves or sheets of music, tiling papers, &c., for reading;and consists in a novel construction, combination, and arrangement ofparts, which have for their object to produce a simple, effective, andcheap leaf or sheet holder, as will be fully set forth hereafter.

Figure 1 is a representation of the holder as attached to the music-restot' a piano. Fig. 2 is an enlarged view of the clamping device, and Fig.3 is a transverse section of Fig. 2.

The holder is composed of a strip of sheet metal, A, one edge, a, ofwhich is bent up at a right angle, while the other edge, b, is turnedover on the same side, in the manner shown at Fig. 3, so as to form agroove or recess, in which a bar, B, is inserted. This bar is narrowerthan the space between the edge of the slot 1) and the clamping-edge aof the metal plate A, and, conscquentl y, is capable of motion toward orfrom the clampingredge of the plate, so as to clamp the paper, 0,inserted between it and the flange a. The plate A has a transverse slotcut in its bottom, and the bar B hasa hole bored in its middle, throughwhich and the slot in the plate a screw, (1, passes, and is screwed intothe music-rest 1), thus keeping the bar B stationary, while the slot inthe plate allows of the latter receiving a transverse movement. The barB is cut partially away, and provided with inclines at c c on its edge,occupyin g the groove of the plate A, and opposite these inclines theedge of the groove 1) is slotted. U U are wedges, which may beconstructed of wood or metal, and are furnished with project-ions f,which pass through the slots in the edge of the groove 1), and by whichthe wedges are operated. The inclines of the wedges correspond withthose on the bar B,

and on operating them the bar is clamped against the flange a of theplate A, and any thing placed between the edge of the bar B and theflange a is firmly held. 9 71 is a springlateh, composed of the spring 9and pin h, and is designed to secure the holder in a vertical positionby the bar depressing the spring and entering between it and the pin ll.

0n closing up the instrument to which the device is attached, should itslength interfere with the folding of the board, it may be turned aroundon the screw to a horizontal position.

It is evident that my device is adapted and could be used for variousother purposes than holding 1in1sic-lea\-'es-as, for instance, it couldbe employed for files of newspapers, letters, bill-heads, &c., or with aslight modification, which would not involve invention, it could be usedfor blocking writing-paper, and several other analogous uses.

'When the device is used separately from the rest I), a nut will be usedon the end of the screw cl to hold the parts A B together.

The device is very simple in construction, and, when used to hold leavesof music, obviates the great inconvenience of the sheets slipping ottthe rest or bending under their weight.

1 cl aim- 1. In combination with the rest 1), the plate A, clamp-bar B,with its wedgesurfaces 'c a, screw (1, and wedges O O, constructed andoperating in the manner and for the purpose specified.

2. As a new and improved article of manufacture, the device for holdingsheets of paper composed of the plate A, with bent edges (0 b, bar B,with wedge-shaped parts 6 a, screw (7, and clamping-wedges G G,constructed and operating suliist-antially as described and specified.
